The results of the SPEC CPU2006 bzip2 benchmark running on an AMD Barcelona has an instruction count of 2.389E12, an execution time of 750 s and a reference time of 9650 s. Find the CPI if the clock cycle time if 0.333 ns. Find the SPEC ratio. Find the increase in CPU time if the number of instructions of the benchmark is increased by 10% without affecting the CPI. Find the increase in CPU time if the number of instructions of the benchmark is increased by 10% and the CPU is increased by 5%. Suppose that we are developing a new version of the AMD Barcelona processor with a 4GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15%. The execution time is reduced to 700s and the new SPEC ratio is 13.7. Find the new CPI. This CPI value is larger than obtained in part a as the clock rate was increased from 3 GHz to 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why? By how much has the CPU time been reduced? For a second benchmark, libquantum, assume an execution time of 960 ns, CPI of 1.61 and clock rate of 3GHz. If the execution time reduced by an additional 10% without affecting the CPI and with a clock rate of 4GHz, determine the number of instructions. Determine the clock rate required to give a further reduction in CPU time while maintaining the number of instructions and with the same CPI. Determine the clock rate if the CPI is reduced by 15% and the CPU time by 20% while the number of instructions is unchanged.
